In his trilingual Preface, Kober writes:
The founding of the European Patent Office 20 years ago was the first step on the road to a unified patent in Europe. The success of the European patent system demonstrates the extent to which this process meets the needs of inventors, researchers and companies alike. The number of filings is one measure of this success, but so is the fact that an ever-growing number of states and international groupings are modernising their own patent systems on the basis of this model. Despite this gratifying situation, the development of the patent protection system in Europe must not be allowed to rest. For regardless of another record number of patent filings and an initial substantial reduction in the EPO's procedural fees, applicants made their expectations clear in the year under review: European patents must cost less, they must have a unitary character and be uniformly enforceable, and they must also provide reliable protection for new technologies. The European Commission addressed these issues in its Green Paper on the Community patent and incorporated them in its proposals for extending the system. During Luxembourg's presidency of the EU, patent experts from the worlds of politics, business and patent applicants commented on the Green Paper. The watchword of this exercise was: "One Europe, one currency, one patent". The way in which the results are put into practice will determine the nature of the European Patent Organisation.
